People (generally) have lost touch with nature and the ability to do things for themselves, be self-reliant, is diminishing which I believe is a bad thing. I'm not saying that everyone needs to have highly developed skills like some of us, just that being able to do a few self sustaining things is an advantage.
I think you probably agree.
Have you got some skills that help you be more self reliant? First aid, electrical, mechanical and other such skills?
In Nature I am sure to die. At home, it may seem silly, but I keep a paper DIY encyclopedia that I still consult from time to time when I need to fix something at home.
As for first aid, even if it is by profession, I have knowledge in emergency intervention, I am accredited as a trauma expert.
